GNOME Calendar has gotten *so good*, it just handles ICS files, multi-day events, multiple calendars, and mismatched timezones so well now. Hands down my favorite calendar app on any platform. If there's a "most improved app award", surely it must be a contender.
@nathandyer That's so amazing! I've used it on #postmarketos for a while now but it felt a little too minimalist. Still have to wait for the update to show up in the repo though 😅
